SPECIFICATION forming part of Letters Patent Ne. 284,237, dated Setembera, 1883,

Application filed November 22, 1882. (No model.)

To all whom it may, concern.-

. Beitjknown that I, FRANK L. ROCKWELL, I of Chicago, county of Cook,and State of Illinois, have invented a new and useful Improve- I ment inDouble Faucets, of which the following is a full, clear, and exactdescription, that will enable others to make and use the same, referencebeing had to the accompanying draw'- ings, and to letters of referencemarked there on, forming a part of this specification. This inventionrelates more especiallyyto that class of faucets intended for use inconnection with stationary washbasins, whereby either hot or cold .watermay be received. through the same discharge, or both at the same time,both passages being regulated by one handle, as will be hereinafter morefully set forth, and described in detail. I I

Figure'l is a top view of a device embodying my improvement; Fig. 2, anend eleva tion, Fig. 3, avertical transverse section; Fig. 4, a verticallongitudinal section, and Fig. 5 a detached detail. I I l Referring tothe drawings, A represents'a cylindrical body or shell, having thelateral projecting parts A A B is the hot and B the cold waterconnections, which are formed integral with the ends A A; and B thedischarge-pipe common to both, which forms an integral part of .the bodyA. I

The water-valves G O, placed in a horizontal plane on each side of thevertical spindle D, are of a cylindrical tapering form, the smaller endor ends being made square, and projecting-into the parts A A as shown inFig. 4 of the drawings. The square end a of these valves engages withthe correspondinglyshaped recess a in the innenside of the clampingdisksa" a". The outer side of these disks is provided with a small squareend, fitting intoasquare recess in the perforated locking flange orflanges b b, through which passes the thumb set-screw 0". The threadedend of this set-screw engages with the correspondingly-threaded recessin the clamping disk or disks a" a These disks are provided with thecentral flange, b which abuts against the annular shoulder b and isthereby prevented from moving outward beyond thispoint. The

locking-flanges b b" are provided with the pro- 2 grasp for adjustingthe same. The opposite end'of the valve 0 is provided with the flangeIf, leaving an annular groove in back. of the same for the packing-diskd. This endof the valve is recessed and threaded to receivethecorrespondingly-threaded spindle D, which is provided with the cross-baror elongated head Of, theends of which are provided with the notches d,as shown in Fig. 5 of the drawing's. I These notched ends are adapted toengage with projecting ribs cast on the interior surface of the shell A,and are exact duplicates of the ribs a (shown in Fig. 3 of the w I Ijecting cars at, forming a convenient fingerdrawings,) and which serveas guides for the valves moving in a horizontal plane, vent a rotarymovement.

The peculiar operation of this device requires a little differentconstruction in the valve 0' from that of the valve G, just described.The valve O has a large recess for the reception of the enlarged :partd", from which extends the threaded valve-spindle (1 into the smallerthreaded recess, as shown in Fig. 4 of the drawings. The enlarged head Dforming an integral part of the valve-spindle d", is provided with theelongated opening or slot (1*, and the projecting notched ends dengaging with the ribs (1?, which prevents a rotary movement of thevalve parts. The packing-disk d is placed onthe valve 0', back of theflange (l and has an annular seat on the interior of the inclosingshell,asshown in Fig. 4 of the drawings, which represents but prethis valveclosed, while the opposite or companion valve 0' is open for the inflowof water, as indicated bythe arrows in Fig. 4 of the drawings. Thesevalves open inwardly by the pressure of water. The locking-flanges b band set screw or screws 0 serve the purpose of drawing the valves to aclose seat, and also prevent these parts from leaking.

That part of the vertical operatingstem D in line with the valves 0 O isprovided with the threelateral projecting camsE E E ar-v ranged in astaggering manner, as shown in Figs. 3 and 40f the drawings. The middlecam,E, is adapted to impinge on the cross-bar G ofthe valve C as theoperating-spindle is rotated for the purpose of closing the same,

while the companion cams pass above. and be! low without coming incontact with the valve 0. The middle cam is set somewhat quartering onthe stem relative to the upper and lower cams, which lie in a parallelplane. Now, when the stem D is rotated to the position shown in Fig. 3of the drawings, the long end of the handle being just the opposite fromthe positionshown in Fig. 4, the valve 0 is opened, and as the stem isrotated farther the middle cam projects into the elongated opening (1*,and does not come in contact with the valve 0, so that the stem may beturned clear around until the upper and lower cams come in contact withthe head D above and below the opening d By this arrangement the middlecam serves to close the valve 0, and cannot be brought in contact withthe companion valve, no matter to what position the stem D may berotated, the same arrangement existing in regard to the upper and lowercams which close the valve 0.. This form of construction permits ofwater being drawn through either valve alternately; or, by turning thelong end of the handle back from the front, both valves are thrown openat the same time, and when rotated to the opposite point both valves areclosed. The stem D may be rotated clear around in either direction. Thethrow or distance the valves open is regulated by turning in or out theadjustable spindles D and (1 which in creases or lessens the distancebetween the cams and theimpinging-points.

The stem D has formed integral therewith the flange G, which has aconical or beveled bearing-surface with the packing-collar G, and formsa ground joint, so that no leakage can occur around the stem. The edgeof the packing-collar G has an annular bearing in the top of theinclosing-shell A, the interposed packing-ring f serving to form a tightjoint. The lower projecting end of the stem is provided with the loosescrew-collar f having the guide-lugs f 2 f which fit into correspondingopenings or grooves, f in the under side of the shell A. The flange H onthe extreme lower end of the stem D serves to retain the loosescrew-collar in place, and the guide-lugs prevent a rotary movement, butat the same time allow a vertical adjustment. The screw-cap H is adaptedto engage With the collar f, and has a bearing in the under side of theshell A, the interposed recessed packing-ring h forming a tight joint.By tightening on this screw-cap, all the bearing's and joints on thestem D are brought to a perfectly-tight bearing.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a double faucet, as described, a cylindrical body, consisting ofthe shell A, having the chambered projections or valve-chambers A A, thedouble connections B B, and the discharge-pipe B formed integral,substantially as described. I
